Mesa ${next_version} Release Notes / ${today}
%if bugfix:
Mesa ${next_version} is a new development release. People who are concerned
with stability and reliability should stick with a previous release or
wait for Mesa ${version[:-1]}1.
%else:
Mesa ${next_version} is a bug fix release which fixes bugs found since the ${version} release.
%endif
Mesa ${next_version} implements the OpenGL ${gl_version} API, but the version reported by
glGetString(GL_VERSION) or glGetIntegerv(GL_MAJOR_VERSION) /
glGetIntegerv(GL_MINOR_VERSION) depends on the particular driver being used.
Some drivers don't support all the features required in OpenGL ${gl_version}. OpenGL
${gl_version} is only available if requested at context creation.
Compatibility contexts may report a lower version depending on each driver.
Mesa ${next_version} implements the Vulkan ${vk_version} API, but the version reported by
the apiVersion property of the VkPhysicalDeviceProperties struct
depends on the particular driver being used.
SHA256 checksum
TBD.
